Preheat oven to 400° F. Let pie crust stand at room temp. for 15 min. For topping, in bowl, combine flour, brown sugar, cinnamon, and butter. Blend with a pastry blender. Add pecans to mixture.
Mix well, set aside. For tart, roll pie crust into a 13" circle using a lightly floured roller.
Peel, core, and slice apples. Cut slices crosswise in half, layer apples evenly over crust to within 1 inch of edge of crust. Spread 1/2 cup of pie filling over apples. Sprinkle topping over apples.
Fold outer edge of pastry over filling to form rim (pastry will cover outer edge of filling only).
Bake 30-35 min or until crust is golden brown. Cool slightly. Also great served with vanilla ice cream with remaining pie filling.
